摘要

利用ATP—EMTP软件平台

建立了无功补偿电容器投切操作的仿真计算模型

模拟了系统投、切操作可能引起的过电压、过电流现象及其影响因素

对无功补偿系统中的电磁暂态过程进行了分析。仿真计算结果表明:无功补偿电容器组投入时产生的合闸涌流和切除时产生的重燃过电压是对系统危害最严重的电磁暂态过程。文章对限制重燃过电压的措施也进行了讨论

并在此基础上计算了安装保护后设备所承受的最大过电压

为系统的安全运行提供了依据。

Abstract

The simulation calculation model of reactive compensation capacitor in switching operation is established with ATP-EMTP software platform

the overvoltage

overcurrent and other effect factors are simulated and the electromagnetic transient process of the reactive power compensation system is analyzed.Simulation calculation results show that

the switching inrush current and reignition overvoltage occur respectively during the reactive power compensation capacitor switching on and off

the electromagnetic transient process are the most critical danger to the system.The measures on limiting reignition is also discussed and based on this

the maximum withstand overvoltage of the equipment is calculated after installing protection

the system safety operation’s reliable basis is provided.
